At this moment it is OK. We are to be in Nashville 8:30 am and I am concerned. Keep an eye on what is coming out of AR. I expect north of Paducah KY may be worse or at least that is the case historically speaking. Here in Murray it was in the lower 60's on Tue and hit 70F with sun yesterday so roads were not as cold as they will be say in Jan so that is a help.
No one knows at this point but you should see reports in the morning showing you where the ice/snow line may be. The Nashville them was about 44 a few hours ago and only to become freezing at about 6 PM on Friday.
Be careful and which you a safe trip to be with the family.
